Altra Olympus 275 Review [After 200+ Miles!]

The Altra Olympus 275 is one of the first pairs of Altras I’ve run in.

After years of wanting to try them, I reached out to Altra, asking to review a pair of their shoes. They sent me the Olympus 275 (and the Experience Wild 2 — review coming soon).

With 200+ miles run in them (including two races), I’m excited to bring you my thoughts on these shoes. What Altra got right, what could be improved, and, ultimately, who the shoe is for.

Disclosure: Altra sent these at no cost after I asked to review them. No payment. Opinions are mine.

I’m not reviewing lug depth with calipers. I’m reviewing what most runners actually care about: comfort over hours, grip when it matters, stability on tired legs, and whether I’d reach for this shoe again.

With that said, let’s check out the Altra Olympus 275.

Altra Olympus 275 Overview

The Altra Olympus 275 gets your attention right away, especially in the Nickelodeon colorway (at least that’s what I’m calling it).

It comes in two options, this green, blue, black, and reddish-orange option that I have and a taupe/black for men. On the women’s side, you can choose between coral/black and a black/lime green option.

The stack height immediately stands out when you look at the shoe, especially compared to other Altra shoes. With a massive pillow looking cushion underneath the foot, it’s pretty hard to miss. But Altra sticks to its zero-drop platform and FootShape toe box that fans know and love.

Altra Olympus 275

The Altra Olympus 275 is a max-cushion trail shoe built for long days in the mountains. With a 33 mm stack, Vibram® Megagrip outsole, and Altra’s signature FootShape fit, it delivers plush comfort without sacrificing confidence on varied terrain.

The upper has a MATRYX build, which is more rip- and tear-resistant to beef up the durability a bit. Whether it’s rocks, roots, or the lurking trail gremlins — it’s built to stand up to almost anything the trail throws at it.

Underneath is a Vibram outsole. If you’ve ever run in Vibram before, you know how well they grip and grab the trail and rocks to keep you stable.

And that’s no different with the Olympus 275 as they’ve brought that same grippy formula to this shoe.

I wore it across everything from buffed singletrack to rocky, wet trails and two races, and the shoe stayed consistent. And I can’t tell you how relieving that is after coming from Salomon shoes where the grip is…well, not so reliable (I still love you, Salomon).

So, overall, Altra appears to have delivered another solid shoe to their lineup, and one of the firsts to their “ultra-premium” style. And, with Altra saying they “went all in on tech so you can go all out on the trail”, the only question is if it delivers.

How The Olympus 275 Feels (After 200+ Miles)

I love running in these because they let me forget about my shoes and focus on the trail.

Overall Ride: “Out-Of-Sight, Out-Of-Mind”

They make me genuinely excited to hit the trails for long distance runs. And that’s thanks to the entire ride and fit of the shoe.

I’m not thinking about grip. I’m not thinking about cushion. I’m not thinking about hot spots or my foot sliding around. I can just run.

And that’s honestly refreshing out of a shoe. For years, I would be extremely cautious if I were running in a pair of Salomon’s and I hit wet pavement. Suddenly, the entire terrain would feel like a sheet of ice, and I was terrified I was about to injure myself.

That’s not the case with the Olympus 275. Give me any terrain, and almost any distance, and the ride is going to be great.

So great, you won’t even think about it.

Cushion & Protection: Plush, But Not Sloppy

Underfoot, the cushion sits right in the middle, which is great because it gives enough protection that sharp rocks don’t bite, but not so soft that you feel sloppy late in the run.

The cushion holds pretty well over longer distances and efforts. I took it on a 3-day 50K stage race and I honestly expected the cushion to give out across the effort.

But, it didn’t. Day after day, they still felt ready to go (and probably even more than I was).

Fit & Lockdown: Roomy Up Front, Secure In The Heel

Up top, the shoe basically disappears.

The scree sleeve did a solid job keeping out most rocks, dirt, and dust. And that classic Altra toe box gives your forefoot room to splay, which was a nice feeling compared to Salomon’s more narrow toe box I’m used to.

I worried a bit if it’d be too much room and my foot would slide around as a result, but the heel and lacing system locked my foot down tight and with little movement from my foot.

I’ve tried Hoka shoes in the past. And even though I wasn’t a fan of the shoes overall, I did like how much room my feet had.

Best comparison I can give: it’s like taking the roominess I liked in Hoka and combining it with the heel lockdown I’m used to from Salomon. And it’s a beautiful combo.

Stability & Stack Height: Confident, But Respect The Height

I felt stable in these overall, mostly because the lockdown is solid and the outsole gives you a lot of confidence when the trail gets rooty, rocky, or slick.

But let’s be real: this is still a tall shoe.

On smoother trail or steady climbs, I barely notice it — it’s the off-camber stuff and technical descents where the height matters most. I wouldn’t say I felt unstable, but the stack height definitely made me more cautious on off-camber sections and technical descents.

If you like max cushion and you’re okay dialing it back a notch on technical descents, they feel great.

Zero-Drop Note (Read This If You’re New To Altra)

If you’re new to zero-drop, I’d start with shorter easy runs for a couple weeks before making these your default long-run shoe.

Now, a lot of this is probably me getting used to the Altra profile and pushing it a bit further than I should have in the shoes. But, it’s something to keep in mind if you’re someone who’s never worn a zero-drop shoe before.

What I Like About The Olympus 275 👍

(If you skipped here: I’ve put 200+ miles on these across technical trail and long efforts — this is the short version.)

1. Grip That Reduces Second-Guessing

The Vibram Megagrip outsole gives me “stop thinking about your feet” confidence on wet rock, roots, and technical trail.

2. Comfort That Holds Up Deep Into Long Days

These are built for the long game. The cushion feels protective without turning sloppy, even when fatigue sets in.

3. The Scree Sleeve Is Actually Useful

It did a solid job keeping out most rocks, dirt, and dust — small feature, big quality-of-life upgrade on gritty trails.

What I Don’t Like About The Olympus 275

I wouldn’t be doing my job if I wasn’t pointing out a few dislikes about the shoe (though calling them dislikes isn’t entirely accurate).

1. The Stack Height Is A Lot

This is a max-cushion shoe, and the height is noticeable.

Most of the time I felt stable, but on sloped singletrack and technical descents (especially when my legs were tired) I had to be a little more intentional with foot placement.

Skip these if: you prefer low-to-the-ground trail shoes, you want a lot of ground feel, or you get nervous on uneven terrain.

2. Zero-Drop Takes Some Getting Used To

This was one of my first Altras, and the zero-drop platform was mostly fine… until I ramped too quickly and noticed some calf/Achilles tightness on a bigger effort.

If you’re new to zero-drop, here’s the safe ramp:

• Week 1–2: 2–3 short easy runs (20–40 minutes) in the Olympus
• Week 3–4: one longer easy run, keep everything else in your usual shoes
• After: start using them for long trail days

That’s not medical advice, just the conservative approach that would’ve saved me some soreness.

Would I Recommend Buying the Altra Olympus 275?

Yes — with one condition: I’d keep them as my long-run / ultra shoe, and I’d respect the stack height on technical descents.

For long days, the comfort + grip combo is exactly what I want.

So, the ultimate question and this is The Travel Runner after all, so should you Pack It, Test It, or Skip It?

My verdict: Test It (leaning Pack It if you like max cushion).

• PACK IT if you want max cushion + legit grip for long trail days and don’t mind a tall stack.
• TEST IT if you’re curious but new to zero-drop—ease in over a few weeks first.
• SKIP IT if you want ground feel, prefer low-stack shoes, or hate shoes that feel tall.
